Accessibility: DatePicker ValueHelp button invisible in screen reader

[shartf]

What is the issue and how can we reproduce it?

1. Activate screen reader on macOS
2. Focus DatePicker input field
3. Try to focus valueHelp button with Ctrl-Alt-Right arrow
   .

Error:

Focus will jump over the value help button not noticing its existence

Expected behavior:

ValueHelp button can be focused and clicked.

I have read #3504 but it is not clear to me, how a user relying on screen reader only should discover that there is a valueHelp and that they need to press F4 to trigger it?

Which OpenUI5 version is your project targeting?

1.141.2

Is the issue device- or browser-specific?

No response
